BRAKE FOR MARINE VESSELS.

To all whom it may concern:

Be it known that I, EMIL E. KoL'rKo, a citizen of the United States,residing at VVaterbury, in the county of New Haven and State ofConnecticut, have invented new and useful Improvements in Brakes forMarine Vessels, of which the following is a specification. 1

This invention relates to brakes for marine vessels, the object in viewbeing to provide in connection with a pair of movable braking wingsmoimted on opposite sides of the vessel and adapted to turn onsubstantially vertical axes, simple and effective mechanism "whereby thesaid braking wings may be operated either to release the same and permitthem to open to their operative position, or to draw the same inward totheir housed or folded position.

A further object of the invention is to provide novel and eflicientmeans for looking said wings in their folded or inoperative positions,combined with means for tripping the locking device when it is desiredto release said wings and permit them to assume their working positions.

With the above and other objects in view,

the invention consists in the novel construction,- combination andarrangement of parts, as will hereinafter be more fully described,illustrated and claimed. Q I

In the accompanying drawings :Figure 1 is a plan view of the forwardportion of a marine vessel showing the mechanism of this inventionapplied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is aninside face view of one of the wings. Fig. 4L is a detail perspectiveview of the keeper bar or locking device.

Referring to the drawings, 1 designates a portion of the hull of amarine vessel, the same being shown in plan view in Fig. 1 and in sideelevation in Fig. 2.

In carrying out this invention I provide a pair of wings 2 located atopposite sides of the bow of the vessel and extending any suitabledistance belowthe water line, the said wings being jointed at theirrearedges as shown at 3 to the hull of the vessel so that said wings mayswing outwardly and inwardly on substantially vertical axes. At theirforward extremities the wings 2 are deflected outwardly or provided withflanges t which are adapted to lie in parallel relation to the oppositesides of the forward stem 5 of the vessel. so as to be Specification ofLetters Patent.

engaged by a keeper bar 6 which is substantially U -Shaped in crosssection so as to embrace and hold both of the flanges 4 of the wingswhen the latter are folded inwardly. The keeper bar 6 is arranged in asubstantially vertical plane and is pivotally mounted intermediate itsends at 7 on a suitable bracket 8 shown for convenience as fastened tothe deck of the vessel. The keeper bar 6 by reason of its shape isadapted to simultaneously embrace and hold both flanges 1 and inaddition thereto said keeper bar is provided with a plurality of sets ofrearwardly diverging fingers 9 adapted to bear against the outersurfaces of the wings 2 to serve as an additional safeguard against theaccidental outward mcvement of said wings.

The wings 2 are provided at their rear edges with inwardly extendingarms 10 which cross or intersect each other as shown in Fig. 1, theinner ends of said arms being arranged in front of a trip lever 11 whichis fulcrumed about centrally at 12 on a supporting bracket 13 also shownas secured to The lower arm of the lever 11 is adapted tocoiiperate withthe arms 10 for the purpose of thrusting the arms 10 in a forwarddirection to start the leading edges of the wings 2 outwardly. The lever11 is operated by means of a chain 14 one end of which is connected tothe upper extremity of the keeper bar 6 at the point 15 while the otherend of said chain is wound upon one section 16 of a double windlassdesignated generally by the reference character A. This Windlass isadapted to be operated by any suitable power, either hand power orengine power as may be preferred. The chain 14 is primarily used tooperate the keeper bar 6 so as to swing the same forward to the dottedline position shown in Fig. 2 for the purpose of releasing the leadingedges of the wings. In order to operate the lever 11, a stop or lug 17is fastened on the chain 1 1 and adapted to come in contact the wings.Therefore, when the sec of the windlass is revolved in one .LlUll, thekeeper bar 6 is first operated and subsequently thereto the lever 11 isactuated to trip the wings by means of the arms 10. As soon as'the wingsstart outwardly, they are caught by the rush of water past the sides ofthe vessel and moved outwardly to their limit. Around another section 18of the windlass A are wound chains or cables 22 which extend in oppositedirections around guide pulleys 23, said cables or chains beingterminally connected at 944: to bridles 25 on the inner faces of thewings 2 as illustrated in Fig. The chains 22 are used primarily to drawthe wings 2 back against the hull of the vessel after the latter hascome to a standstill and they may also serve as means for limiting theoutward movement of the wings and staying said wings when they reach.their outer limit of movement.

As illustrated in Fig. 2, the wings 2 may be provided with port holes 26to register with the port holes 27 in the vessel when the wings arefolded against the sides of the vessel. 28 designates a guide pulleyaround. which the chain 14 passes. Channels or gutters 29 and 30 arepreferably used to form run-ways for the chains 19 and 22 and if desiredthese run-ways may be in the form of pipes or tubes.

From the foregoing description it will now be understood that bydperating the chain and windlass mechanism, the keeper bar 6 is firstthrown out of locking position and afterward by the cooperation of thelever 11 and the arms 10, the leading edges of the braking wings arestarted outwardly after which they are thrust to the full limit of theiroutward i'i'iovement by the action of the water thereon. The parts arerestored to their folded posit-ions also by means of the chain andwindlass mechanism, the windlass section 1.8 being first operated todraw the wings back to their folded position, after which the windlasssection 16 is operated and acts first to restore the trip lever 11 toits normal. position and subsequently to restore the keeper bar (3 toits wing-locking position.

The brake hereinabove described will bring the vessel to a standstill ina very short distance and avoid many of the accidents which sofrequently occur by reason of the inability of the engines to check theforwardmovement of the vessel in time to avert such accidents.

What I claim is 1. The combination with a marine vessel, of brakemechanism comprising a pair of wings pivotally mounted at their rearedges to turn on substantially vertical axes, the forward edges of saidwings lying on opposite sides of the front stem of the vessel and beingadapted to swing outwardly away from said stem, a substantially verticalkeeper bar pivotally supported intermediate its ears and adapted in oneposition to embrace the leading edges of said wings when foldedinwardly, and windlass and chain mechanism connected with said keeperbar for moving said bar to wing-engaging and disengaging position.

2. The combination with a marine vessel, of brake mechanism comprising apair of wings pivotally mounted at their rear edges to turn onsubstantially vertical axes, the forward edges of said wings lying onoppo site sides of the front stem of the vessel and being adapted toswing outwardly away from said stem, a substantially vertical keeper barpivotally supported intermediate its ends and adapted in one position toembrace the leading edges of said wings when folded inwardly, andwindlass and chain mechanism connected with said keeper bar both aboveand below the pivot thereof, for moving said bar to wing-engaging anddisengaging posit-ion.

3. The combination with a marine vessel, of brake mechanism comprising apair of wings pivotally mounted at their rear edges to turn onsubstantially vertical axes, the forward edges of said wings lying onopposite sides of the front stem of the vessel and being-adapted toswing outwardly away from said stem, a substantially vertical keeper barpivotally supported intermediate its ends and adapted in one position toembrace the leading edges of said wings when folded inwardly, windlassand chain mechanism connected with said keeper bar for moving said barto wing-engaging and disengaging position, and set-s of wingholdingfingers on said bar.
